Ya beat me to it.
Looks good to me, his run animation is a little different, more circular and less eliptical. I saw lots of nods to levels like those blue Marble Garden Zone wheels, but the levels themselves look a bit more subtly inspired rather than ripped off directly. He still has the homing attack which is fine with me, he had little differences in his move sets between the 1st 3 so...(also the roller coast track reminded me of North Corel, lol.
Tails carrying Sonic underwater too sounds interesting, I'm still not quite sure of the purpose of their 69 attack.
I'm excited, I wonder if this is actually gonna continue from episode 1...how will they explain why you need to collect the emeralds again?
